I'll preface this by saying I own both a M&P 9C and full size. I've had them for several years and had no issues with them at all.
I took my new Shield out yesterday to shoot for first time, this was after a good cleaning.
When I pulled the slide back it got stuck in the open position. I had to bang it with the but of my hand to make it close. Then I tried to put some rounds through it. First magazine the slide stuck open four times, each time I had to bang the slide to close it. This not a FTF or FTE, the slide is simply stuck open. Long story short.... this continued (less frequent) as I put more rounds through.
It wasn't until after 100 rounds+ that I was able to shoot an entire magazine with the slide sticking.
All total I put about 250 rounds through it with less and less problems.
Has anybody else had this experience? I did a internet search and saw where a few folks had same problem but it was when the Shield first came out.
I'm going to clean it again and shot it some more but I'm a little concerned. This was to be my main carry gun and failing just once could be a problem.
I plan on call S&W and see what the have to say.

That's odd. The slide on mine works perfectly, but I haven't shot it yet. I will shot it tomorrow morning. Report back on what S&W have to say. I'm curious.

Never with a new gun. Did you check the slide and frame for signs of wear? Any shiny spots through the finish? Glock uses a copper anti-seize compound that they recommend you don't clean off during initial shooting. Don't know if your pistol had the same or similar.

I remember reading stories about this on the S&W forums. Not sure what the answer was but I do remember reading it.

Y'all clean these things way to much.

Took mine out the box. Got some steel cased ammo and shot about 100 rounds with no problems what so ever.

Ill go dump some more rounds through it another day.

I'm not cleaning it though thats for sure. Not for a while anyway.

I don't know what's wrong, but there can't be ANYTHING wrong w/ a gun for cc. This doesn't sound like a break in issue.

Nope. Mine is fine. Had a problem with trigger not cocking after I chambered it a few times but turns out I really need o push that slide in all the way. I mean really push it in. Problem solved.

The only problem I ever had with my Shield was one magazine that I always had trouble getting through without misfeeds. I guess that must have gotten broken in, because I quit having that problem. My slide seemed really hard to pull back at first, but that may have been my not having experience with a semi-auto handgun.

Have read several reports of this involving some of the most recently manufactured Shields.

Clearly S&W has/had a QA/QC problem recently. They seem to have overestimated demand, and built a sh*t load of Shields to meet demand that wasn't these (Hence all the rebates). This apparently lead to shoddy workmanship.

My Shield is one of the earliest models. Never any problem -- yet.

If I owned one like you have, I've ship it back to S&W and insist that it be inspected/repaired/tested/returned. Even if the symptoms dissipate on their own, I wouldn't trust it until you run ~1000 rounds thru it with zero malfunctions. (This is my personal reliability test for any self-defense weapon.
